Make playlist and albumviews the same, and add play and shuffle button

[mickenordin]

Hello! Thank you for a great project! I have tried several subsonic apps, and this one has the most potential IMHO!

I do have some UI suggestions though.

I think it would make a lot of sense if the playlists used the same layout as the album view, where an image is displayed on the left and a download button is displayed to the right. Further more I think it would make sense to put a play button, as well as a shuffle (and mane a repeat) button next to this.

Thanks again!
